A coated wire includes a steel alloy coated with a coating comprising one or more amino alkoxy-modified silsesquioxane compounds selected from the group consisting of an amino alkoxy-modified silsesquioxane, an amino/mercaptan co-alkoxy-modified silsesquioxane, an amino/blocked mercaptan co-alkoxy-modified silsesquioxane, or a salt of one or more thereof. A rubber composition and a process for coating wire is also disclosed.

It has been discovered that the use of a plasticizer, an ester of a cyclohexanepolycarboxylic acid, especially a 1,2-cyclohexanedicarboxylic acid ester, that is environmentally non-toxic, can replace environmentally unfriendly phthalate plasticizers, such as dioctyl phthalates used in vulcanizable rubber compositions, especially for tires, on a one to one weight basis (phr) without sacrificing beneficial rubber properties.

Old, spent or worn tires are recycled by removing non-rubber components such as belts, beads, and fabric, and grinding the remaining cured rubber into fine sized particles. The ground particles generally replace equivalent amounts of rubber and additives in various tire formulated components such as tire treads. Good physical properties of the end product are retained.
